Abstract
We have developed a very efficient procedure for carrying out the cyclopropanation reaction of α,β-unsaturated aldehydes with diethyl bromomalonate using an O-TMS-diarylprolinol as a catalyst. We have found that the use of water as reaction medium results in a remarkable beneficial effect on the reaction, allowing it to be performed without the need to incorporate one equivalent of an external base, which is the case in other similar methodologies reported. In addition, several new chiral pyrrolidines have been prepared that have potential for improved ability as a catalyst for this transformation in aqueous media. In this context, a modified O-TMS-diarylprolinol incorporating a hydrophobic alkyl side chain has been identified as a promising catalyst for this reaction.
